  • spring 3 uploadify giving 404 Error

    - by Rajkumar
    I am using Spring 3 and implementing Uploadify. The problem is, the files are updating properly but it is giving HTTP Error 404, on completion of file upload. I tried every possible solution, but none of them works. The files are uploaded. Values are storing in DB properly, only that i am getting HTTP Error 404. Any help is appreciated and Thanks in advance. The JSP Page $(function() { $('#file_upload').uploadify({ 'swf' : 'scripts/uploadify.swf', 'fileObjName' : 'the_file', 'fileTypeExts' : '*.gif; *.jpg; *.jpeg; *.png', 'multi' : true, 'uploader' : '/photo/savePhoto', 'fileSizeLimit' : '10MB', 'uploadLimit' : 50, 'onUploadStart' : function(file) { $('#file_upload').uploadify('settings', 'formData', {'trip_id' :'1', 'trip_name' :'Sample Trip', 'destination_trip' :'Mumbai','user_id' :'1','email' :'[email protected]','city_id' :'12'}); }, 'onQueueComplete' : function(queueData) { console.log('queueData : '+queueData); window.location.href = "trip/details/1"; } }); }); The Controller @RequestMapping(value="photo/{action}", method=RequestMethod.POST) public String postHandler(@PathVariable("action") String action, HttpServletRequest request) { if(action.equals("savePhoto")) { try{ MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest)request; MultipartFile file = multipartRequest.getFile("the_file"); String trip_id = request.getParameter("trip_id"); String trip_name = request.getParameter("trip_name"); String destination_trip = request.getParameter("destination_trip"); String user_id = request.getParameter("user_id"); String email = request.getParameter("email"); String city_id = request.getParameter("city_id"); photo.savePhoto(file,trip_id,trip_name,destination_trip,user_id,email,city_id); photo.updatetrip(photo_id,trip_id); }catch(Exception e ){e.printStackTrace();} } return ""; } spring config <bean class="org.springframework.web.multipart.commons.CommonsMultipartResolver" id="multipartResolver"> <property name="maxUploadSize" value="10000000"/> </bean>

  • Connecting Error to Remote Oracle XE database using ASP.NET

    - by imsatasia
    Hello, I have installed Oracle XE on my Development machine and it is working fine. Then I installed Oracle XE client on my Test machine which is also working fine and I can access Development PC database from Browser. Now, I want to create an ASP.Net application which can access that Oracle XE database. I tried it too, but it always shows me an error on my TEST machine to connect database to the Development Machine using ASP.Net. Here is my code for ASP.Net application: protected void Page_Load(object sender, EventArgs e) { string connectionString = GetConnectionString(); OracleConnection connection = new OracleConnection(connectionString); connection.Open(); Label1.Text = "State: " + connection.State; Label1.Text = "ConnectionString: " + connection.ConnectionString; OracleCommand command = connection.CreateCommand(); string sql = "SELECT * FROM Users"; command.CommandText = sql; OracleDataReader reader = command.ExecuteReader(); while (reader.Read()) { string myField = (string)reader["nID"]; Console.WriteLine(myField); } } static private string GetConnectionString() { // To avoid storing the connection string in your code, // you can retrieve it from a configuration file. return "User Id=System;Password=admin;Data Source=(DESCRIPTION=" + "(ADDRESS=(PROTOCOL=TCP)(HOST=myServerAddress)(PORT=1521))" + "(CONNECT_DATA=(SERVICE_NAME=)));"; }

  • How can I add the column data type after adding the column headers to my datatable?

    - by Kevin
    Using the code below (from a console app I've cobbled together), I add seven columns to my datatable. Once this is done, how can I set the data type for each column? For instance, column 1 of the datatable will have the header "ItemNum" and I want to set it to be an Int. I've looked at some examples on thet 'net, but most all of them show creating the column header and column data type at once, like this: loadDT.Columns.Add("ItemNum", typeof(Int)); At this point in my program, the column already has a name. I just want to do something like this (not actual code): loadDT.Column[1].ChangeType(typeof(int)); Here's my code so far (that gives the columns their name): // get column headings for datatable by reading first line of csv file. StreamReader sr = new StreamReader(@"c:\load_forecast.csv"); headers = sr.ReadLine().Split(','); foreach (string header in headers) { loadDT.Columns.Add(header); } Obviously, I'm pretty new at this, but trying very hard to learn. Can someone point me in the right direction? Thanks!

  • Javascript API not working for Chrome or Safari on JW Player 5.9

    - by Lando
    I am working on a custom interface for the JW Player which displays the current track title and has play/pause, next track, previous track and volume toggle buttons.

  • Casting to a struct from LPVOID - C

    - by Jamie Keeling
    Hello, I am writing a simple console application which will allow me to create a number of threads from a set of parameters passed through the arguments I provide. DWORD WINAPI ThreadFunc(LPVOID threadData) { } I am packing them into a struct and passing them as a parameter into the CreateThread method and trying to unpack them by casting them to the same type as my struct from the LPVOID. I'm not sure how to cast it to the struct after getting it through so I can use it in the method itself, i've tried various combinations (Example attatched) but it won't compile. Struct: #define numThreads 1 struct Data { int threads; int delay; int messages; }; Call to method: HANDLE hThread; DWORD threadId; struct Data *tData; tData->threads = numThreads; tData->messages = 3; tData->delay = 1000; // Create child thread hThread = CreateThread( NULL, // lpThreadAttributes (default) 0, // dwStackSize (default) ThreadFunc, // lpStartAddress &tData, // lpParameter 0, // dwCreationFlags &threadId // lpThreadId (returned by function) ); My attempt: DWORD WINAPI ThreadFunc(LPVOID threadData) { struct Data tData = (struct Data)threadData; int msg; for(msg = 0; msg<5; msg++) { printf("Message %d from child\n", msg); } return 0; } Compiler error: error C2440: 'type cast' : cannot convert from 'LPVOID' to 'Data' As you can see I have implemented a way to loop through a number of messages already, I'm trying to make things slightly more advanced and add some further functionality.

  • CallbackValidator called with empty string

    - by Paolo Tedesco
    I am writing a custom configuration section, and I would like to validate a configuration property with a callback, like in this example: using System; using System.Configuration; class CustomSection : ConfigurationSection { [ConfigurationProperty("stringValue", IsRequired = false)] [CallbackValidator(Type = typeof(CustomSection), CallbackMethodName = "ValidateString")] public string StringValue { get { return (string)this["stringValue"]; } set { this["stringValue"] = value; } } public static void ValidateString(object value) { if (string.IsNullOrEmpty((string)value)) { throw new ArgumentException("string must not be empty."); } } } class Program { static void Main(string[] args) { CustomSection cfg = (CustomSection)ConfigurationManager.GetSection("customSection"); Console.WriteLine(cfg.StringValue); } } And my App.config file looks like this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="customSection" type="CustomSection, config-section"/> </configSections> <customSection stringValue="lorem ipsum"/> </configuration> My problem is that when the ValidateString function is called, the value parameter is always an empty string, and therefore the validation fails. If i just remove the validator, the string value is correctly initialized to the value in the configuration file. What am I missing?

  • Simplest way to debug an android bluetooth application

    - by intiha
    I am trying to test and build a sample android application that can simply connect to a BT server to send and receive a few packets. Since the emulator has no support what is the next best thing to test BT communication? Can I just run a code that acts as a server on my laptop and dumps BT connection onto a console? Do I have to write this code, or is their a simple tool that saves me that hassle? One more thing, I have windows 7, and currently I attach to my PC an anycom USB BT adapter. This is able to show up my nexus one as a BT device. I can pair to my laptop but connection always fails. When it tries to pair I have tried both 0000 and 1234 as suggested on my nexus, but in my connection list it still lists my laptop as paired but not connected. Any idea why? I searched for this problem and apparently people talk about rebooting and power cycling BT, but these solutions dont work for me. Thanks. Affan.

  • Strange XCode debugger behavior with UITableView datasource

    - by Tarfa
    Hey guys. I've got a perplexing issue. In my subclassed UITableViewController my datasource methods lose their tableview reference depending on lines of code I put inside the method. For example, in this code block: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { // Return the number of sections. return 3; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { // Return the number of rows in the section. return 5; } // Customize the appearance of table view cells. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { id i = tableView; static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell... return cell; } the "id i = tableView;" causes the tableview to become nil (0x0) -- and it causes it to be nil before I ever start stepping into the method. If I insert an assignment statement above the "id i = tableview;" statement: CGFloat x = 5.0; id i = tableView; then tableview retains its pointer (i.e. is not nil) if I place the breakpoint after the "id i = tableView;" line. In other words, the breakpoint must be set after the "id i = tableView"; assignment in order for tableView to retain its pointer. If the breakpoint is set before the assignment is made and I just hang at that breakpoint for a bit then after a couple of seconds the console logs this error message: Assertion failed: (cls), function getName, file /SourceCache/objc4_Sim/objc4-427.5/runtime/objc-runtime-new.mm, line 3990. Although the code works when I don't step through the method, I need my debugger to work! It makes programming kind of challenging when your debugging tools become your enemy. Anyone know what the cause and solution are? Thanks.

  • iPhone: Creating a hierarchy-based table navigation.

    - by Jack Griffiths
    Hi there, I've tried to ask this before, but nothing got answered. Basically, I would like someone to explain to me how to create a table, which when a cell is tapped, pushes the user to the next view for that cell. I have this so far: Click here to view what I have. I would further like to, say when CSS is tapped, it goes to a new view which has another table in it. This table would then take the user to a detail view, which is scrollable and you can switch pages through it. I would appreciate longer, more structured tutorials on how to do each and every bit to get it to work. Here's my array in my implementation file: - (void)viewDidLoad { arryClientSide = [[NSArray alloc] initWithObjects:@"CSS", @"HTML", @"JavaScript", @"XML", nil]; arryServerSide = [[NSArray alloc] initWithObjects:@"Apache", @"PHP", @"SQL", nil]; self.title = @"Select a Language"; [super viewDidLoad]; } and my .h: @interface RootViewController : UITableViewController <UITableViewDelegate, UITableViewDataSource> { IBOutlet UITableView *tblSimpleTable; NSArray *arryClientSide; NSArray *arryServerSide; } My current code crashes the script, and this error is returned in the console: Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UITableViewController loadView] loaded the "NextView" nib but didn't get a UITableView.' If that error is the source of why it's not pushing, then an explanation of how to remedy that would also be appreciated Many thanks, Jack

  • Mocking Autofac's "Resolve" extension method with TypeMock

    - by Lockshopr
    I'm trying to mock an Autofac resolve, such as: using System; using Autofac; using TypeMock.ArrangeActAssert; class Program { static void Main(string[] args) { var inst = Isolate.Fake.Instance<IContainer>(); Isolate.Fake.StaticMethods(typeof(ResolutionExtensions), Members.ReturnNulls); Isolate.WhenCalled(() => inst.Resolve<IRubber>()).WillReturn(new BubbleGum()); Console.Out.WriteLine(inst.Resolve<IRubber>()); } } public interface IRubber {} public class BubbleGum : IRubber {} Coming from Moq, the syntax and exceptions from TypeMock confuse me a great deal. Having initially run this in a TestMethod, I kept getting an exception resembling "WhenCalled cannot be run without a complementing behavior". I tried defining behaviors for everyone and their mothers, but to no avail. Then I debug stepped through the test run, and saw that an actual exception was fired from Autofac: IRubber has not been registered. So it's obvious that the static Resolve function isn't being faked, and I can't get it to be faked, no matter how I go about hooking it up. Isolate.WhenCalled(() => ResolutionExtensions.Resolve<IRubber>(null)).WillReturn(new BubbleGum()); ... throws an exception from Autofac complaining that the IComponentContext cannot be null. Feeding it the presumably faked IContainer (or faking an IComponentContext instead) gets me back to the "IRubber not registered" error.

  • C# Windows Service doesn't seem to like privatePath

    - by SauerC
    I wrote a C# Windows Service to handle task scheduling for our application. I'm trying to move the "business rules" assemblies into a bin subdirectory of the scheduling application to make it easier for us to do updates (stop service, delete all files in bin folder, replace with new ones, start service). I added <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <probing privatePath="bin;"/> </assemblyBinding> </runtime> to the service's app config and it works fine if the service is run as a console application. Problem is when the service is run as a windows service it doesn't work. It appears that when windows runs the service the app config file gets read properly but then the service is executed as if it was in c:\windows\system32 and not the actually EXE location and that gums up the works. We've got a lot of assemblies so I really don't want to use the GAC or <codeBase>. Is it possible to have the EXE change it's base directory back to where it should be when it's run as a service?

  • Jquery - binding click event to a variable

    - by Kayote
    All, I am really stuck/ confused at this point. I have an array with 6 items in it. Each item in the array is dynamically filled with elements using jquery '.html' method. However, I cannot seem to be able to attach/ bind an event to this dynamically created variable. As soon as the browser gets to the problem line (see the area labeled 'PROBLEM AREA'), I get a 'undefined' error, which is really confusing as all the previous code on the very same variable works just fine. var eCreditSystem = document.getElementById("creditSystem"); var i = 0; var eCreditT = new Array(6); // 6 members created which will be recycled function createCreditTransaction () // func called when a transaction occurs, at the mo, attached to onclick() { if (i < 6) { eCreditT[i] = undefined; // to delete the existing data in the index of array addElements (i); } else if (i > 5 || eCreditT[i] != undefined) { ... } } function addElements (arrayIndex) // func called from within the 'createCreditTransaction()' func { eCreditT[i] = $(document.createElement('div')).addClass("cCreditTransaction").appendTo(eCreditSystem); $(eCreditT[i]).attr ('id', ('trans' + i)); $(eCreditT[i]).html ('<div class="cCreditContainer"><span class="cCreditsNo">-50</span>&nbsp;<img class="cCurrency" src="" alt="" /></div><span class="cCloseMsg">Click box to close.</span><div class="dots"></div><div class="dots"></div><div class="dots"></div>'); creditTransactionSlideOut (eCreditT[i], 666); // calling slideOut animation console.log(eCreditT[i]); // this confirms that the variable is not undefined /* ***** THE PROBLEM AREA ***** */ $(eCreditT[i]).on ('click', function () // if user clicks on the transaction box { creditTransactionSlideBackIn (eCreditT[i], 150); // slide back in animation }); return i++; }

  • System.Math.Round bug?

    Hi All, I was writing a function for rounding a number to two places. And I found a bug when I was trying to round specific values. So, I ran the code: class Program { static void Main(string[] args) { int limit = 100; for (int number = 0; number <= limit; number++) { Console.WriteLine((System.Math.Round((double)(number+0.995),2,MidpointRounding.AwayFromZero))); } } } And I found that: 8.99 9.99 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 32.99 33.99 34.99 35.99 36.99 37.99 38.99 39.99 numbers are not rounded to their next value. When I run the same code till 1500: I get the numbers: 8.99 9.99 32.99 33.99 34.99 35.99 36.99 37.99 38.99 39.99 1024.99 1025.99 1026.99 1027.99 1028.99 1029.99 1030.99 1031.99 1032.99 1033.99 1034.99 1035.99 1036.99 1037.99 1038.99 1039.99 1040.99 1041.99 1042.99 1043.99 1044.99 1045.99 1046.99 1047.99 1048.99 1049.99 1050.99 1051.99 1052.99 1053.99 1054.99 1055.99 1056.99 1057.99 1058.99 1059.99 1060.99 1061.99 1062.99 1063.99 1064.99 1065.99 1066.99 1067.99 1068.99 1069.99 1070.99 1071.99 1072.99 1073.99 1074.99 1075.99 1076.99 1077.99 1078.99 1079.99 1080.99 1081.99 1082.99 1083.99 1084.99 1085.99 1086.99 1087.99 1088.99 1089.99 1090.99 1091.99 1092.99 1093.99 1094.99 1095.99 1096.99 1097.99 1098.99 1099.99 1100.99 1101.99 1102.99 1103.99 1104.99 1105.99 1106.99 1107.99 1108.99 1109.99 1110.99 1111.99 1112.99 1113.99 1114.99 1115.99 1116.99 1117.99 1118.99 1119.99 1120.99 1121.99 1122.99 1123.99 1124.99 1125.99 1126.99 1127.99 1128.99 1129.99 1130.99 1131.99 1132.99 1133.99 1134.99 1135.99 1136.99 1137.99 1138.99 1139.99 1140.99 1141.99 1142.99 1143.99 1144.99 1145.99 1146.99 1147.99 1148.99 1149.99 1150.99 1151.99 1152.99 1153.99 1154.99 1155.99 1156.99 1157.99 1158.99 1159.99 1160.99 1161.99 1162.99 1163.99 1164.99 1165.99 1166.99 1167.99 1168.99 1169.99 1170.99 1171.99 1172.99 1173.99 1174.99 1175.99 1176.99 1177.99 1178.99 1179.99 1180.99 1181.99 1182.99 1183.99 1184.99 1185.99 1186.99 1187.99 1188.99 1189.99 1190.99 1191.99 1192.99 1193.99 1194.99 1195.99 1196.99 1197.99 1198.99 1199.99 1200.99 1201.99 1202.99 1203.99 1204.99 1205.99 1206.99 1207.99 1208.99 1209.99 1210.99 1211.99 1212.99 1213.99 1214.99 1215.99 1216.99 1217.99 1218.99 1219.99 1220.99 1221.99 1222.99 1223.99 1224.99 1225.99 1226.99 1227.99 1228.99 1229.99 1230.99 1231.99 1232.99 1233.99 1234.99 1235.99 1236.99 1237.99 1238.99 1239.99 1240.99 1241.99 1242.99 1243.99 1244.99 1245.99 1246.99 1247.99 1248.99 1249.99 1250.99 1251.99 1252.99 1253.99 1254.99 1255.99 1256.99 1257.99 1258.99 1259.99 1260.99 1261.99 1262.99 1263.99 1264.99 1265.99 1266.99 1267.99 1268.99 1269.99 1270.99 1271.99 1272.99 1273.99 1274.99 1275.99 1276.99 1277.99 1278.99 1279.99 1280.99 1281.99 1282.99 1283.99 1284.99 1285.99 1286.99 1287.99 1288.99 1289.99 1290.99 1291.99 1292.99 1293.99 1294.99 1295.99 1296.99 1297.99 1298.99 1299.99 1300.99 1301.99 1302.99 1303.99 1304.99 1305.99 1306.99 1307.99 1308.99 1309.99 which are not rounded to next number! Has anyone any idea about why its happening for these specific numbers!

  • What is the Difference between GC.GetTotalMemory(false) and GC.GetTotalMemory(true)

    - by somaraj
    Hi, Could some one tell me the difference between GC.GetTotalMemory(false) and GC.GetTotalMemory(true); I have a small program and when i compared the results the first loop gives an put put < loop count 0 Diff = 32 for GC.GetTotalMemory(true); and < loop count 0 Diff = 0 for GC.GetTotalMemory(false); but shouldnt it be the otherway ? Smilarly rest of the loops prints some numbers ,which are different for both case. what does this number indicate .why is it changing as the loop increase. struct Address { public string Streat; } class Details { public string Name ; public Address address = new Address(); } class emp :IDisposable { public Details objb = new Details(); bool disposed = false; #region IDisposable Members public void Dispose() { Disposing(true); } void Disposing(bool disposing) { if (!disposed) disposed = disposing; objb = null; GC.SuppressFinalize(this); } #endregion } class Program { static void Main(string[] args) { long size1 = GC.GetTotalMemory(false); emp empobj = null; for (int i = 0; i < 200;i++ ) { // using (empobj = new emp()) //------- (1) { empobj = new emp(); //------- (2) empobj.objb.Name = "ssssssssssssssssss"; empobj.objb.address.Streat = "asdfasdfasdfasdf"; } long size2 = GC.GetTotalMemory(false); Console.WriteLine( "loop count " +i + " Diff = " +(size2-size1)); } } } }

  • Internal "Tee" setup

    - by RadlyEel
    I have inherited some really old VC6.0 code that I am upgrading to VS2008 for building a 64-bit app. One required feature that was implemented long, long ago is overriding std::cout so its output goes simultaneously to a console window and to a file. The implementation depended on the then-current VC98 library implementation of ostream and, of course, is now irretrievably broken with VS2008. It would be reasonable to accumulate all the output until program termination time and then dump it to a file. I got part of the way home by using freopen(), setvbuf(), and ios::sync_with_stdio(), but to my dismay, the internal library does not treat its buffer as a ring buffer; instead when it flushes to the output device it restarts at the beginning, so every flush wipes out all my accumulated output. Converting to a more standard logging function is not desirable, as there are over 1600 usages of "std::cout << " scattered throughout almost 60 files. I have considered overriding ostream's operator<< function, but I'm not sure if that will cover me, since there are global operator<< functions that can't be overridden. (Or can they?) Any ideas on how to accomplish this?

  • Core Data, Bindings, value transformers : crash when saving

    - by Gael
    Hi, I am trying to store a PNG image in a core data store backed by an sqlite database. Since I intend to use this database on an iPhone I can't store NSImage objects directly. I wanted to use bindings and an NSValueTransformer subclass to handle the transcoding from the NSImage (obtained by an Image well on my GUI) to an NSData containing the PNG binary representation of the image. I wrote the following code for the ValueTransformer : + (Class)transformedValueClass { return [NSImage class]; } + (BOOL)allowsReverseTransformation { return YES; } - (id)transformedValue:(id)value { if (value == nil) return nil; return [[[NSImage alloc] initWithData:value] autorelease]; } - (id)reverseTransformedValue:(id)value { if (value == nil) return nil; if(![value isKindOfClass:[NSImage class]]) { NSLog(@"Type mismatch. Expecting NSImage"); } NSBitmapImageRep *bits = [[value representations] objectAtIndex: 0]; NSData *data = [bits representationUsingType:NSPNGFileType properties:nil]; return data; } The model has a transformable property configured with this NSValueTransformer. In Interface Builder a table column and an image well are both bound to this property and both have the proper value transformer name (an image dropped in the image well shows up in the table column). The transformer is registered and called every time an image is added or a row is reloaded (checked with NSLog() calls). The problem arises when I am trying to save the managed objects. The console output shows the error message : [NSImage length]: unrecognized selector sent to instance 0x1004933a0 It seems like core data is using the value transformer to obtain the NSImage back from the NSData and then tries to save the NSImage instead of the NSData. There are probably workarounds such as the one presented in this post but I would really like to understand why my approach is flawn. Thanks in advance for your ideas and explanations.

  • Need advice on comparing the performance of 2 equivalent linq to sql queries

    - by uvita
    I am working on tool to optimize linq to sql queries. Basically it intercepts the linq execution pipeline and makes some optimizations like for example removing a redundant join from a query. Of course, there is an overhead in the execution time before the query gets executed in the dbms, but then, the query should be processed faster. I don't want to use a sql profiler because I know that the generated query will be perform better in the dbms than the original one, I am looking for a correct way of measuring the global time between the creation of the query in linq and the end of its execution. Currently, I am using the Stopwatch class and my code looks something like this: var sw = new Stopwatch(); sw.Start(); const int amount = 100; for (var i = 0; i < amount; i++) { ExecuteNonOptimizedQuery(); } sw.Stop(); Console.Writeline("Executing the query {2} times took: {0}ms. On average, each query took: {1}ms", sw.ElapsedMilliseconds, sw.ElapsedMilliseconds / amount, amount); Basically the ExecutenNonOptimizedQuery() method creates a new DataContext, creates a query and then iterates over the results. I did this for both versions of the query, the normal one and the optimized one. I took the idea from this post from Frans Bouma. Is there any other approach/considerations I should take? Thanks in advance!

  • java logging nightmare and log4j not behaving as expected with spring + tomcat6

    - by maverick
    I have a spring application that has configured log4j (via xml) and that runs on Tomcat6 that was working fine until we add a bunch of dependencies via Maven. At some point the whole application just started logging part of what it was supposed to be declared into the log4.xml "a small rant here" Why logging has to be that hard in java world? why suddenly an application that was just fine start behaving so weird and why it's so freaking hard to debug? I've been reading and trying to solve this issue for days but so far no luck, hopefully some expert here can give me some insights on this I've added log4j debug option to check whether log4j is taking reading the config file and its values and this is what part of it shows log4j: Level value for org.springframework.web is [debug]. log4j: org.springframework.web level set to DEBUG log4j: Retreiving an instance of org.apache.log4j.Logger. log4j: Setting [org.compass] additivity to [true]. log4j: Level value for org.compass is [debug]. log4j: org.compass level set to DEBUG As you can see debug is enabled for compass and spring.web but it only shows "INFO" level for both packages. My log4j config file has nothing out of extraordinary just a plain ConsoleAppender <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"> <!-- Appenders --> <appender name="console" class="org.apache.log4j.ConsoleAppender"> <param name="Target" value="System.out" /> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%-5p: %c - %m%n" /> </layout> </appender> What's the trick to make this work? What it's my misunderstanding here? Can someone point me in the right direction and explain how can I make this logging mess more bullet proof?
